centos上的安裝和調試freeradius

來源:互聯網
上載者:User

1、使用yum安裝即可,確定安裝的是freeradius2,而不是1。如果以前又freeradius,先卸載

     yum remove freeradius
     安裝
     yum install freeradius2
     yum install freeradius2-utils  //這個含radtest,使用者測試

     預設freeradius是使用files方式認證使用者,如果不使用資料庫,到此安裝就搞定了

2、安裝完成後就修改設定檔。

     vi /etc/raddb/users
     找到steve,注釋去掉,將steve改成你的使用者名稱。可以建立多個使用者,如下:
     dalon   Cleartext-Password := "testing"
     test    Cleartext-Password := "testing123"

3、 測試

      可執行檔為 /usr/sbin/radius
      /usr/sbin/radius -X       //debug模式運行,可以看到詳細過程。
      radtest 測試server是否能響應:    
      radtest test testing localhost 0 testing123
      test和testing分別為使用者名稱和密鑰,對於設定檔users裡面的內容。
      localhost為設定檔clients.conf中的內容,預設針對localhost密鑰為testing123
      0 意思為NAS-PORT 0,預設為0,所以不用配置。見檔案 /etc/raddb/radiusd.conf中配置,如下:
      listen {
       ipaddr = *       //監聽IPV4所有地址
#        ipv6addr = ::
        port = 0        //nas-port
        type = acct
#       interface = eth0
#       clients = per_socket_clients
}

測試正確的結果如下(下面是測試IPV6):

[root@CentOS ~]# radtest -6 test test123 ::1 0 testing123
Sending Access-Request of id 44 to ::1 port 1812
        User-Name = "test"
        User-Password = "test123"
        NAS-IPv6-Address = ::1
        NAS-Port = 0
        Message-Authenticator = 0x00000000000000000000000000000000
rad_recv: Access-Accept packet from host ::1 port 1812, id=44, length=20

4、將伺服器改成監聽IPV6

需要修改檔案

a) /etc/raddb/radiusd.conf
    將兩個listen {}中 ipaddr = *  注掉,ipv6addr = ::   取消注釋
b) /etc/raddb/clients.conf
將localhost中的監聽地址改成ipv6的,如下:
client localhost {
        ipv6addr = ::1  # any.  ::1 == localhost

建立一組client(下面的例子是3000::/64網段為例,也可以使用::/0):
client 3000::/64 {
        secret          = testing123
        shortname       = ipv6client     //為區別名,和別的組不一樣即可
}

5. 驗證通過的debug資訊:

rad_recv: Access-Request packet from host 3000::abcd port 60378, id=232, length=45
        User-Name = "dalon"
        User-Password = "testing"
# Executing section authorize from file /etc/raddb/sites-enabled/default
+- entering group authorize {...}
++[preprocess] returns ok
++[chap] returns noop
++[mschap] returns noop
++[digest] returns noop
[suffix] No '@' in User-Name = "dalon", looking up realm NULL
[suffix] No such realm "NULL"
++[suffix] returns noop
[eap] No EAP-Message, not doing EAP
++[eap] returns noop
[files] users: Matched entry dalon at line 76
++[files] returns ok
++[expiration] returns noop
++[logintime] returns noop
++[pap] returns updated
Found Auth-Type = PAP
# Executing group from file /etc/raddb/sites-enabled/default
+- entering group PAP {...}
[pap] login attempt with password "testing"
[pap] Using clear text password "testing"
[pap] User authenticated successfully
++[pap] returns ok
# Executing section post-auth from file /etc/raddb/sites-enabled/default
+- entering group post-auth {...}
++[exec] returns noop
Sending Access-Accept of id 232 to 3000::abcd port 60378
Finished request 29.

Ready to process requests.


6.在mysql中添加使用者進行測試

mysql;
use radius;
insert into radcheck (username,attribute,op,value) values ('test','User-Password',':=','pass123');
exit;
radtest test pass123 127.0.0.1 0 testing123
看到“rad_recv: Access-Accept” 則認證成功。

7.如果授權其他主機訪問radius認證,可以在radius server的clients.conf添加授權

vim /etc/raddb/clients.conf
添加
client 192.168.50.64 {
    ipaddr = 192.168.50.64
    secret      = testing123
}

登入192.168.50.64
yum -y install freeradius-utils
radtest test pass123 192.168.50.65 0 testing123
